EX9520AR - RS232 to RS485 / RS422 converter (isolated RS422 / RS485)

The RS232 to RS485 Converter enables you to easily link devices communicating via RS232 with a RS485 network. In a RS485 network you may control up to 256 devices. Furthermore you may use 2 RS232 to RS485 Converters to build a RS232 bridge via RS485 and thereby extend the maximum cable length from a few meters to 1200 m. You may enlarge the range of your RS485 network with a RS485 Repeater.

The RS232 to RS485 Converter is capable of auto flow control and automatic baud rate switching. You may instead of the EX9520AR get the EX9520AR+ which can be powered with 9V - 48VDC instead of 10V - 30VDC. The RS232 to RS485 Converter can be operated in extended temperature range and the RS422 / RS485 input is isolated.

Features:

• Full-Duplex RS422
• RS422 / RS485 isolated

• extended temperature range -25°C - +75°C
• range up to 1200m
